Network administrators in charge of internetworks that implement Cisco-supported protocols and Cisco products will find Internetworking Troubleshooting Handbook valuable; it's an excellent reference to solving common networking challenges encountered on Cisco-based internetworks.
The authors assume that administrators will already have hands-on experience in configuring, administering, and troubleshooting a network, as well as how to configure routers, switches and bridges; they also assume users will have familiarity with protocols and media that the users's hardware has been configured to support.
The book has been sectioned into seven parts: "Introduction to Troubleshooting," "Hardware, Booting, and Media Problems," "Troubleshooting Desktop and Enterprise Routing Protocols," "Troubleshooting Serial Lines and WAN Connections," "Troubleshooting Bridging and Switching Environments," and "Troubleshooting Other Internetwork Problems."
Part seven is actually a great set of appendixes: "Creating Core Dumps" (causes of router crashes can often be identified with a full copy look at the memory image, or core dump, and this is the instruction set), "Memory Maps" (for selected product platforms, designed to assist technically qualified users knowledgeable in concepts of low-level operating systems, bus structures, and address mapping), "Technical Support Information" (a template for gathering thorough information before presenting it to a technical support representative), "References and Recommended Reading," and finally, "Troubleshooting Worksheets" (to be used as guidelines for compiling relevant facts en route to isolating an internetwork problem).
Blessed with an extensive index, excellent organization, and a successful visual design throughout, Internetworking Troubleshooting Handbook is a solid guide for learning via a banquet of multiple problem scenarios. It will discipline users to develop first-class strategies toward the ultimate goals of reducing downtime, improving network performance, and enhancing network reliability.
A comprehensive, ambitious, professional, and well conceived book, heartily recommended.
